I have some photos, shot indoors, some with flash and some with just the incandescent lighting. They're family shots, taken impromptu. In the flash shots, the walls are the correct colour. The others are far too warm, of course. There's no white in shot. Is there a way in LR of setting temperature and tint so that a non-white colour matches that in another shot? I've fiddled with the sliders but I'm getting nowhere near the right balance.
Yes, I should have used a WhiBal. But I didn't.
